Super happy with this purchase,was flipping out for a while cuz usps tracking was saying still in delivery from 9am,it was in mailbox at my dad's at 505 but hadn't updated,he got home after six n said it was there,I went n got it came home.n as I got here I got update from usps saying at 505 it was delivered...bull.... update crap haha but I am happy.hope this excess liquid goes away .
